Another aspect could be the interaction between the different power systems. The chakra in Naruto and the ki in Dragon Ball are both forms of energy. In the fanfic, there could be a situation where Naruto discovers a way to convert his chakra into ki or vice versa. This would open up a whole new world of possibilities for his character, such as being able to sense ki signatures like the Dragon Ball characters do, which would give him an edge in battle and in tracking down opponents.
In a 'naruto in dragon ball fanfic', a possible crossover is the sharing of combat strategies. Naruto's creative ninja tactics could be combined with the more straightforward but powerful fighting styles in Dragon Ball. Like Naruto using his shadow clones in combination with Goku's Kamehameha wave. He could send a horde of clones towards an opponent and then have them all fire off a mini - Kamehameha, creating a very unique and powerful attack.
One interesting crossover could be Naruto learning ki techniques from the Dragon Ball characters. For example, he might learn how to fly using ki, which would be a new and exciting addition to his ninja skills.
There are fanfics where the Dragon Balls are introduced into the Naruto universe. This could lead to all sorts of chaos. Naruto and his friends might be on a quest to gather the Dragon Balls for a noble cause, like bringing back a fallen comrade. At the same time, the villains from Dragon Ball Z could be tempted by the power of the tailed beasts in the Naruto world. It would be a really exciting mix of two great anime universes.
One interesting crossover could be a battle between Naruto's Rasengan and Goku's Kamehameha. It would be epic to see the different energy forms collide. Maybe Naruto could learn some of Goku's training techniques and vice versa, like Naruto trying to achieve Super Saiyan levels of power or Goku learning about chakra control.
In Naruto x Dragon Ball Z fanfiction, a really cool concept is the sharing of training methods. Naruto could learn about the gravity training that Goku does on Planet Namek. This would significantly boost his physical strength and speed. On the other hand, Goku might be interested in Naruto's chakra control training, which could potentially help him with his ki control in a different way. And when it comes to storylines, some fanfictions might involve the search for the Dragon Balls in the Naruto world, with Naruto and his friends joining Goku and his crew to find them, leading to all sorts of adventures and battles along the way.
One interesting crossover could be a battle between Hulk's brute strength and Goku's Super Saiyan power. Maybe in the fanfic, they start off as rivals, with Hulk misunderstanding Goku as a threat to Earth. Their fight would be epic, with Hulk's limitless rage against Goku's increasing power levels. It could also explore how their different universes' power systems interact.
One interesting crossover in fanfiction is when the characters swap their powers. For example, Goku using chakra - based attacks like Naruto's Rasengan, and Naruto being able to transform into a Super Saiyan. It's a really cool concept that flips the normal abilities of the characters on their heads.
One interesting crossover could be Goku meeting Elsa. Goku might be intrigued by Elsa's ice powers and try to spar with her. He could learn a lot about controlling power from Elsa as she has to constantly keep her emotions in check to avoid causing too much ice mayhem, much like how Goku has to control his Saiyan rage.
One interesting crossover could be Ben Tennyson using his Omnitrix to transform into an alien with powers similar to a Saiyan. For example, he could transform into an alien that can increase its power level like a Super Saiyan. Another could be the characters from Dragon Ball Super being intrigued by Ben's ability to change forms so quickly and effortlessly.
A really cool crossover concept could be the sharing of techniques. Spiderman could learn how to use Ki blasts from Goku or Vegeta. In return, he could teach them some of his acrobatic fighting moves. This exchange of skills would create some really unique and exciting battle scenes in the fanfiction, as they combine their different fighting styles to take on common enemies.
In some fanfictions, Goku could team up with Ash. Goku's super strength and ability to fly would be a great asset. He could help Ash in battles against tough opponents like Team Rocket when they use more powerful Pokemon or machinery. Also, Goku might be intrigued by the concept of Pokemon evolution, which is somewhat similar to Saiyan power-ups.
Well, a great aspect of crossovers in their fanfiction could be the battles. Imagine Goku from Dragon Ball Z facing off against Vilgax from Ben 10. Goku's martial arts skills and ki blasts against Vilgax's brute strength and advanced weaponry. And what if Ben, in his alien forms, had to team up with Goku to fight a common enemy? That would make for an exciting story.
